I had this pretty bad for the first few weeks I was taking trazodone to help with sleep (50mg/night, I'm on my second month of it.). I also woke up with some pretty bad headaches along with the stuffy nose.
I know that this all sounds terrible, but my first week or so on the med I slept great and felt great throughout the day. I thought that perhaps the AD effect was getting through the small dose and helping me greatly! However, that did not last long and I have retracted back into a painfully anxious and depressed state.

I am taking it less and less this week as it has been on/off effective anyway.
